Abstract: Attapulgite/copper ferrite (ATP/CuFe2O4) magnetic nanocomposites are prepared through one-pot hydrothermal method using copper chloride, ferric trichloride and ethylene glycol as raw materials.The structure and surface characteristics of the prepared materials are investigated by TEM, EDS, FTIR, XRD and BET.ATP/CuFe2O4 magnetic nanocomposites are used as catalyst for the reduction of 4-nitrophenol to 4-aminophenol in the presence of sodium borohydride at room temperature.Influences of various catalysts, CuFe2O4 coating amount and catalyst dosage on the reduction of 4-NP by NaBH4 are studied.The experiment results show that ATP/CuFe2O4 material with a 50% of CuFe2O4 coating amount exhibits a higher catalytic activity and can make the reaction complete within 7 minutes when its dosage is 5 mg.The repeating and recovering experiments show that this catalyst has good magnetic separation and recycle stability.
